Emulsified oil is a kind of small oil particles about 0.5~25m in diameter, ranging from light brown to dark brown liquid or semi-solid, belonging to the category of metal cutting oil. Its main role is cooling, lubrication for automobile manufacturing, sawing, drilling, grinding and other metal rough processing.
The use of emulsified oil: The use of emulsified oil is closely related to its composition. It is mainly composed of base oil, emulsifier, rust inhibitor, preservative, chelating agent and so on. General base oil is mainly animal and plant oil or mineral oil, which plays a lubricating role in the processing process. The quality of base oil is closely related to the performance of bell cream products. The emulsifier has the function of cleaning and lubricating. On the one hand, the base oil forms a uniform emulsion in water, which has different effects on the stability of the product. The combination of rust inhibitor has a great impact on the rust resistance of the product, so it should be adjusted according to the type of metal processed. Sandan oil and oxazolane derivatives are commonly used as preservatives. Toxicity should be considered in the selection of preservatives. To a certain extent, the composition of emulsified oil determines its functions of lubrication, cleaning, rust prevention and corrosion prevention.
Emulsified oil is mainly used for hydraulic support of integrated mining face. Hydraulic support is one of the key equipment of integrated mining face, which is composed of column, cylinder, beam, base, various control valves and pipes. Bracing, lifting, moving, sliding, and overload protection are systems that transmit and convert energy from pressurized liquids -- high water hydraulic fluids -- to pipes and control elements of a specific structure.
In the metal processing industry, emulsified oil has cooling, lubrication, cleaning, extreme pressure, rust prevention and other functions, widely used in cutting, cutting, grinding, polishing and other processing processes. This machine is suitable for black and non-ferrous metal processing parts, drilling, drilling, hinge, rolling and other common machine tools, improve the cutting durability and cutting efficiency.
Generally speaking, emulsified oil refers to adding 30%~10% (mass ratio, Hetung) to 70%~90% of the fuel (gasoline, diesel or heavy oil), and then adding 0.5%~1% additives through special equipment for emulsification. The oil is made into a tarpaulin water molecular group. The smaller and more uniform the particles are, the longer the stable period of emulsified oil is. Generally speaking, the oil and water of emulsified oil are separated within 1 to 6 months, and the performance of emulsified oil is worse after demulsification. A large number of molecules, such as surfactants, are adsorbed on the surface of the oil particles of emulsified oil. The surface of oil particles has a double-layer structure. The main method of removing emulsified oil is container float, adding coagulant before air float to stabilize the emulsified oil and improve the removal effect of air float.
To sum up, emulsified oil can save energy and reduce pollution in the combustion of external and internal combustion equipment, and has universal significance for light oil and heavy oil.
